A few pictures of my eCCR electronics playground. Physical testbench setup with development board and the first version custom PCBs. Main features of the first version: solenoid control, ppO2 display for three cells and the ppO2 decision value, two fixed setpoints, some alarms, etc. In the last pictures a prototype HUD setup with LEDs indicating deviation from ppO2 setpoint.
